No, all MORMON things have a Mormon influence! No logical fallacies were made in pointing out the VERY obvious influences of Mormon doctrine on the books; if you choose to ignore or denigrate them, that's your choice.
I made some of these observations to my wife a month ago, in line looking at a supermarket tabloid. I'll admit, I felt a bit slow for not catching on until the third movie, but as I am not a teenage girl, I never bothered to read the books or watch the movies. (I'll further admit to being a fan of Orson Scott Card and Battlestar Galactica, even though they're eeevil Mormon lit, too.)
Well congratulations on finding what you want. But of the items listed, they are not inherently Mormon.
It is only a Mormon influence if you want it to be.
